android - 如何在android中使用xml可绘制创建半圆填充形状？

Question

我想使用 xml drawble 创建一个半实心的圆形形状？

像这样

这是我迄今为止尝试过的努力

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#FCD83500"/>
    <size
        android:width="10dp"
        android:height="5dp"/>
    <corners
        android:bottomLeftRadius="50dp"
        android:bottomRightRadius="50dp"/>
</shape>

使用上面的代码我可以创建半圆，但我不知道如何使半圆透明

我也访问了一些SO帖子，但找不到任何解决方案

• Half circle shape not work
• how to draw a half circle in android
• How to define a circle shape in an Android xml drawable file?

如果需要更多信息，请告诉我。提前致谢。您的努力将受到赞赏。

我已经从矢量图形创建了代码:

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="314.015"
    android:viewportHeight="314.015">
    <path
        android:fillColor="#FCD83500"
        android:pathData="M157.007,0C70.291,0 0,70.289 0,157.007c0,86.712 70.29,157.007 157.007,157.007c86.709,0 157.007,-70.295 157.007,-157.007C314.014,70.289 243.716,0 157.007,0zM31.403,157.015c0,-69.373 56.228,-125.613 125.604,-125.613V282.62C87.631,282.62 31.403,226.38 31.403,157.015z" />
</vector>

输出将是:

现在，如果您想按照您的角度显示:

您可以按如下方式使用:

android:rotation="90"

在你的ImageView

更新TextView可绘制对象:

创建旋转可绘制对象的自定义方法。

private Drawable rotate(Drawable drawable, int degree) {
    Bitmap iconBitmap = ((BitmapDrawable) drawable).getBitmap();

    Matrix matrix = new Matrix();
    matrix.postRotate(degree);
    Bitmap targetBitmap = Bitmap.createBitmap(iconBitmap, 0, 0, iconBitmap.getWidth(), iconBitmap.getHeight(), matrix, true);

    return new BitmapDrawable(getResources(), targetBitmap);
}

使用如下:

Drawable result = rotate(ContextCompat.getDrawable(mContext, R.drawable.ic_round), 90);
yourTextView.setCompoundDrawablesWithIntrinsicBounds(result, null, null, null);

Note: If you will find SVG image as you want then you do now have todo above code. I have tried to find image but didn't found so Rotationcode is necessary here.

希望对您有帮助。

谢谢。
